I bought this item not needing but wanted to give i8t to a friend who did as a gift. To be honest, at such an inexpensive price I figured it would be next to worthless. I tell you now I was pleasantly surprised. This thing sang like a bird, no noise, very sensitive. As good as my $80 clip in the sound hole Lawrence. I am going to share this with my groups on facebook and order another one just to have on hand in case someday I may need it or want to give it away again. I am truly amazed at how good this inexpensive item preforms. Easy to install, just clip it into the sound hole and your ready to go. No batteries required. You will however need an amplifier.
